Security Advisories

About This Page

CTC Union maintains a dedicated Product Security Incident Response Team (PSIRT) to continuously handle externally reported product security vulnerabilities. This page consolidates product security vulnerability advisories that have been confirmed by PSIRT and for which a patch or mitigation has been made available, allowing customers to review the latest security status of the products they use.


Disclosure Principles

To protect the security of customer products, CTC Union generally does not publicly disclose details of a security vulnerability before it has been remediated or an effective mitigation has been made available. Only once a patched version is available for download, or an appropriate mitigation has been provided, will CTC Union publish the corresponding security advisory on this page.
